摘要：
This paper deals with the plane strain problem of determining stress intensity factors and crack energies of a static cruciform crack in an infinite orthotropic elastic medium. The problem is reduced to the solution of two simultaneous singular integral equations with Cauchy-type singularities. Expressions for stress intensity factors (SIF) and crack energies for the case general loading distribution are obtained. Numerical results for some special cases are presented for the Boron-Epoxy composite material. (C) 2000 Elsevier Science Ltd. All rights reserved.
